I used them to buy and sell gift cards in early 2020. Everything went to plan. On the same day they received my gift cards, they paid the money into my bank account. For those gift cards I purchased via voucha.com.au I saved 15 - 20% which equaled about a $50 saving overall. This a lot of money for me! They also did not charge me for the postage, which was a bonus. The cards arrived by post in 3 or 4 days and I used them on the spot without any problems. It's a good idea and I don't believe anyone else is doing this in Australia, so good luck to them!
